Hypothetical tyre question

Juat having thoughts on tyres for the cutdown.
I'm deffo using Continental k62 tyres with 400x10 on the back.
I'm pondering a ponder I've had for many years and never tried.
If I was to put a 300x10 on the front (and this is truly for aesthetic purposes) would it handle like shit?
