Is it possible to convert a Ruger Hawkeye convert from .270 to .35 Whelen?

I have seen this excellent Ruger bolt action, stainless, with open sights, in .270, for sale cheep.

I would love to get it and convert (bore out the barrel?) to .35 Whelen.

Is this possible? Any gunsmith that can do this project?

Thanks.
