I have one that's not feeding well , and wonder if it can - and

I've heard of guys doing it but usually it's just for finishing a job,
like on a weekend and no-obtanium till Monday...

I was working on a Miller 250MP last winter for a friend and I could
find replacement liners for ~$12 on Ebay. This was a liner for .024
to .035 wire. The only hard part was identifying the part number
needed. His gun wasn't easily recognizable and had the part numbers
worn off.

I think you should check replacement pricing first, don't think it will
be that much. Probably around $25 or less...

A new liner and drive roller came in the mail today from USAWeld .
Under 30 bucks for both delivered , $9/liner and $14/roller plus
shipping . The old liner has only had about 12-13 lbs of .025 wire thru
it . I suspect the problem is from infrequent use and some flash rust on
my wire . Try as I might , it's really hard to keep the humidity down in
the shop - I do have a 6k BTU AC unit out there , but don't run it all
the time due to the cost .
