If your willing to pay the big bucks, then I'm sure there is a competent gunsmith who will do it.
Or, like Bonhm16 said, you can just get a Blaser R8, and be done with it.
But, then, you will have a push-feed rifle, and will be assuming ambient temperature as soon as you shoot at a DG animal.
To be clear, I wasn’t advocating for the Blaser… Just saving the Blaser aficionados some time.
I hope the OP comes back to this thread in a year or two to post pics of the exact rifle he was seeking advice on. You know, something beautiful and classy.
