I haven't done an exact calculation, but it seems to me that removing 25% of the curve route through a 12150 (or similar) would take you into the crossing (aka frog) area which would make it a very tricky exercise.

a year or two ago in one of these forums there was a guy, who explained how to.
this pic is from him:

I suspected that it would go too close to the frog. The picture seems to confirm that. I expected someone would have been crazy enough to try this. I wonder how well rolling stock went through that point. Perhaps "the guy" can share his experience if he sees this. Thanks for your responses.

With the brass rails being that close at the crossing, the pickup sliders on LBG locos would definitely touch both rails, creating a short circuit.
FWIW, the point in that photo an early hinged-blade type without the extra insulated sections at the "nose" of the crossing. This also created short circuits, which is why the extra insulation was later added to the crossing assembly.

my thoughts, when i saved the pics:
yes, the smaller frog might lead to short circuits.
but on the other hand, a R1 curve or turnout is 30 cm/300mm/12" long.
half length (6") would be 15° - quarter length (of 7.5 cm/3") 7.5°
the short rail, from where it leaves the frog, must be about 6 cm.
so, leaving the frog alone, just straightening the rails, the turnout should be about 24°.
24° is better than 30° (i think...)
sparing me all the frog-work, leaving just a bit bending to do.
good enough for the gov'mint of my railway...

This might give you a better idea of the issue....
