Julian, I don't think I understand what you are suggesting, because I don't understand what ends the 1290 days in your suggestion. Put it in this sort of form, so I can understand.
Day 1 - the confirmation of the covenant.
Day 220 - the animal sacrifices started again. (2300 days before Jesus returns).
Day 1185 - the AoD image placed in the temple, the Jews begin to flee.
Day 1260 - the two witnesses are killed.
Day 1263.5 - the two witnesses ascend, leaving this world
Day 2475 - the world sees Jesus before the throne of God. (Day 1185 + 1290 days).
Day 2520 - Jesus descends to earth and executes judgement on them gathered to make war on him.

12 And an host was given
him against the daily
sacrifice by reason of transgression, and it cast down the truth to the ground; and it practised, and prospered.
13 Then I heard one saint speaking, and another saint said unto that certain
saint which spake, How long
shall be the vision
concerning the daily
sacrifice, and the transgression of desolation, to give both the sanctuary and the host to be trodden under foot?
14 And he said unto me, Unto two thousand and three hundred days; then shall the sanctuary be cleansed.
Julian, it is not talking
just about the stopping of the daily sacrifice, but also a transgression. The transgression is what makes the temple desolate (another way of saying no praise and worship of the One True God during that time. Until it is cleansed of what makes the temple desolate.)
So there has to be the resumption of the daily sacrifice since it hasn't been done for 2000 years. Then at some point stopped by the little horn person. And then the little horn person does something that is a transgression, lasting until Jesus returns.
All of those activities combined will span the 2300 days.

There are some choices of what causes the desolation. One is the abomination of desolation, that in Daniel 12:11 will be "setup". That doesn't sound like a human being to me, but an object. So I take the
abomination of desolation to be the image the false prophet has made of the person.
Differently, in 2Thessalonians2:4, the person goes into the temple, sits, making his claim to be God.
So that is the "
transgression" of desolation. But transgression against what? Transgressing the covenant he confirmed for 7 years earlier; which, intrinsic to that covenant is to worship the One True God only.
In Daniel 9, Daniel was lamenting over his ancestors had "transgressed" the Mt.
Sinai covenant.
11 Yea, all Israel have
transgressed thy law, even by departing, that they might not obey thy voice; therefore the curse is poured upon us, and the oath that
is written in the law of Moses the servant of God, because we have sinned against him.
The point being is that the transgression of desolation is different from the abomination of desolation.

an act by the person.
