ALL you have to do is add a 40 degree secondary bevel to the blade, and discover a whole new plane. Go on .. do it

p.s. Paul Sellers did the same, and then proclaimed BU planes rubbish. Makes you think ...
One more thing on a bevel up plane besides the bevel angle, don't try to take an 0.030" shaving.
Thick shavings are just asking for tear out, especially with a plane best suited to cut end grain.
