The shorter skirt does help clear the weights but the main concern would the be clearance of the piston below the pin hole. The stock 250 piston with 300 rod and crank pratically sits on the counter weight of the crank at BDC.
300 below pin thickness: 4.5 mm
250 below pin thickness: 6.36 mm
265 below pin thickness: 4.5 mm
This is the 300 piston/rod/crank at BDC:
250 piston/300 rod and crank:
Wiseco 265cc 64mm/300 rod and crank:
250 vs 265 64mm

Alex, I've reached the 50 max photos per post. Can you override it for me as a special request? Currently having to resort to hyperlinking in OP. I should have made another post after the original one for just in case.
