relining artillery luger to 7.65mm luger ?

[lfid]

Im considering a very worn finish artillery luger with very poor bore in 9mm
and want to keep the original exterior as part of a restoration idea

would it be reasonable and safe to have it relined to 30 cal ?
would the rechamber to 30 cal even be possible ?

anybody know of good shop in US to have this or similiar work done / cost ?

does a worn out barrel mean many rounds / lots of heat thru the barrel ?

how much effect on value would poor bore have on a rust reblue restore
that attempts to keep most markings albeit they be softer ?

thanks for any comments / better ideas
