First of all please dont flog me for this question....
I have several "vintage" ebay razors that aren’t anything special, but they shave. Lately, I've been noticing all the super cheapy razors on e-bay that have been specifically noted as razors to stay away from AND of those cheapy razors I’ve actually seen a few where the scales don’t look too horrible.

So I have a question that is purely theoretical and as a total newb I’m not sure of the answer. IF I bought a cheapo with scales that I like (around $15) which also happened to have a similar blade size to my old razors, is there any reason I wouldn’t be able to mount the scales to one of my vintage razors?

Just throwing the idea out there.
Thanks
