That's what I'd do rather than cut up an original FWT. Depending on the condition of the pre-64 you start with, the value it'll lose plus the money you'll put into it will pretty much buy that one. It's really not a bad deal considering the Lyman Alaskan scope and mount would sell for around $300 if you didn't want to keep it. You could also have the barrel re-contoured if it felt too clubby.
JMO,YMMV
