308 caliber spanish mauser 1916 rebarreling back to 7x57

So I have a 308 1916 spanish mauser that i was given as a gift and midway usa has 7x57 green mountain barrels for 87 dollars.

I am wondering if it is feasable to convert this rifle back to it's orginal caliber.

I am aware that the stell block from the magwell would have to be removed.

has anyone here done this kind of conversion, have experiance with this or could maybe recommend a gunsmith who works on these

Also apologies if this topic has already been covered somewere else on the forum

thank you
