yes! I used to be that way, until I decapitated about 100 trees last year.
after you start to see success with grafts, you be more eager to cut beautiful seedling rootstocks to a stump, for promising new cultivars to be grafted on!
your tree is still small enough to cleft graft, or veneer or wedge!
it really isn't too large, or a candidate for top working quite yet!
I say graft it asap!!
and let me know if you need advice.
take care amigo!
