No.
It is impossible to be that, for the reasons above, and more yet to be identified. For instance, the context of Daniel 8 deals with the "daily" and the "yearly" services of the Sanctuary, and thus the "cleansed" portion deals with the Day of Atonement, which takes place once per year, and so 2,300 days of atonement, are 2,300 years unto the anti-typical Day of Atonement. See:
The parallels in Daniel 8 to Leviticus 16 are stunning:
Daniel 8 KJB is steeped in Sanctuary language, from the regular day to day service and the year end time service, the Day of Atonement, for it speaks about a “ram”, a “he-goat”, “four horns”, “the daily”, the “sanctuary”, the “prince of Princes” [High priest, Jesus Christ], the “host”, “saint”, “Gabriel” [the covering cherub who replaced Lucifer, who stands “in the presence of God” [Luke 1:19 KJB]], “transgression” [sin] and “cleansed”, and “truth” [Law, etc], and the 2,300 “evening and morning/s”, “many days”, and “time of the end”, “last end” and etc.
In the sanctuary services [Psalms 77:13 KJB], the cleanse part has to do with the transition from the daily to the yearly [day of atonement] in type and antitype, even as Daniel 8 refers to in imagery [Ram [offering], He-goat [sin offering], Four Horns [as in the golden altar] for making atonement, in both place and people], see Leviticus 16:
Leviticus 16:2,13,14,15 - mercy seat [and cherubim thereon]
Leviticus 16:2-9,11-21,23-34 - High Priest, ministration
Leviticus 16:3,5 - ram
Leviticus 16:4,24,26,27,28,30 - washing/burning, thus cleansing
Leviticus 16:5,7,8,15,24 - [Lord's] goat, sin offering
Leviticus 16:5,9,10,15,16,21,27,30,34 - transgression
Leviticus 16:5,6,7,15,16,17,19,20,21,22,23,24,26,27,28,29,30,31,33,34 - people of God, congregation, camp
Leviticus 16:6,17,20 - atonement [so also Leviticus 23]
Leviticus 16:12,13,18 - with four horns outside on altar of sacrifice and four horns inside golden altar of incense [Daniel 8:13-14,26, etc, Revelation 9:13-15, Oct. 22, 1844]
Leviticus 16:16,19,30,33 - uncleanness of persons and places, needing to be cleansed [vs 19, “cleanse”]
Leviticus 16:34 - end of the daily [evening and morning], now the once in the year
Thus what Daniel 8:14 KJB, reveals is the transition of Christ Jesus [Daniel 8:13 KJB, “certain saint”, the wonderful numberer, who numbers the hairs, stars, sands, kingdoms, times and boundaries, etc] in His Great High Priestly role, from one phase [antitypical daily] to another [antitypical yearly] in the Great Heavenly Sanctuary above, per Daniel, Matthew, Acts, Hebrews, Revelation, etc, and also deals with the peoples of that time [1844] afterward, in their own related cleansing. Thus sanctuary, and host.
Daniel 8:1,4,6,7,20 - Ram
Daniel 8:3,5,6,7,8,9,20,21 - horns [8, 4 outside [altar sacrifice], 4 inside [altar incense' -- 2 on ram, 1 on he-got, 4 on he-goat, 1 from winds]
Daniel 8:5,8,21 - He Goat
Daniel 8:10,13,24,25 - the holy people of God
Daniel 8:11,13,14,25 - certain saint [High Priest Jesus]
Daniel 8:12,13,14,24,25 - transgression
Daniel 8:13,15-17 - one saint speaking, and another saint said - covering cherubims/angels [Gabriel and 'Herald']
Daniel 8:11,12,13-14,26 - daily ongoing [evening and morning] and finally ended, yearly commenced
Daniel 8:14 - cleansed
more in Daniel 9-12 KJB where the atonement is found, which is the re-explanation and expansion of Daniel 8.
There are two sets of 'four horns' in Daniel 8 KJB.
The first set of 'four':
[1] “two horns” of the Ram
[2] the “great” or “notable” “horn” of the He-goat
[3] the “little horn” out of the four winds
The second set of 'four':
[1] the “four notable ones” that came out of the He-goat after the “great” or “notable” “horn”.
There are 8 horns in the sanctuary service.
[1] 4 horns on the altar of sacrifice [Exodus 27:2, 38:2]
[2] 4 horns on the altar of incense [Exodus 30:2, 37:25,26]
Daniel 8:14 KJB - And he said unto me, Unto two thousand and three hundred days; then shall the sanctuary be cleansed.
Which, in Daniel 9, we get the specific timeframe to start in the Medo-Persian Empire.
