Looking at the OP's post it doesn't look like he has money to burn or the most experience shooting long.
His "wants" fall well with in the capabilities of the more sedate 6.5 offerings even if a 140 at 3000 isn't in the cards.
Also as to the actions on hand they could easily be trade/sell fodder for a different action.
Reading between the lines and looking back to projects I've put together I think the OP would be better served with one of the short action 6.5's like the Lapua,Creed, or 260.
Making empties is where it is at and less is often more.
