Picture frame a wood floor to hid a gap

Hello all, I am working on a small house that was built in 1890, the maple wood floor comes about 1.5 inches short of the plaster. To cover it right know they are using a two baseboard the looks only okay. I am curious it it would be smarter to make strait cuts about 2.5 inches from the wall and add a of maple to bring it with in 3/8 of the wall allowing to run a nice single piece base board? Good idea, or I missing something that could be a problem long term?

Making these "straight cuts" to precision required for flooring would be tough. Even with a shooting board or track saw. Then you still be stuck with square edge joints at best [as in no tongue]. Might invite trouble.
Even a 3 element mold sounds preferable, the inner 2 elements could be very low in height. One reason for 2 element base trim in old houses is the tall board won't conform to the floor humps and lows so a thinner 2nd element was used that could be bent to fit.
A bigger concern than making a straight cut with a track saw is avoiding nails. Any cut that you make will have to be the same distance out from each wall. --Highly unlikely that you'll find that "sweet spot" without nails to be the same from each wall.
