Adjusting the shape from Beaver tail to splinter looking at the pictures should cause you no problem but I would have liked to see the complete for end tip that is not in the picture. I do think that the largest problem you will have after re shaping the F/E will be checkering because you will need some form of cradle to hold it, without one it is an up hill struggle. I am biased because I have done a number of Beaver Tail conversions, re shaping is the easy part compered with the final checkering, hope things work out well for you.

The only lessons in my life I truly did learn from where the ones I paid for!
