My guess is it would not retain the sharp point and would round out a tad, but it would stay put if properly notched. Then again, the slight roundedness might a good thing for peoples' nuts and bellies.

You could also cut the t-molding right where the points are (which would leave a seam, but might look better anyway). If it were me, I would first try what leapinlew suggested and if it doesn't work, then cut it there.
