Inbreeding clone only marijuana? Problems?

I've read some of the stuff about breeding. Can you take a clone only plant like purple kush, force it to hermie by stressing it or other means, flower it, and cross it with another purple kush female to get seed? I know this is inbreeding but we do it all the time with dogs to get different "breeds". Essentially it would be making a "pure" breed or actually the "purest" possible breed available in seed with only 1 phenotype. I also know that undesirable characteristics arise from inbreeding, but how bad could those undesirables be when we are only harvesting for the bud? Has anyone seen any "effect" of inbreeding in marijuana before?

yes its called backcrossing bt i think it will be more tendencied to hermie since you stated with a hermie
