There have been a couple of builds using Savage Actions by forum members. Here is a link to the google custom search feature where you can find post regarding Savage actions/builds. Hopefully other members will chime in but I think your plan is doable.
I know the current Savage 6 ARC bolt actions use a magazine and the feeding has always been an issue with Savage builds in 6.5 Grendel. With the 6 ARC there is now a magazine available with the three round flush fit or 12 round from the Savage 110 Tactical 6 MM ARC.
I know there are internal magazine designs with flush floor plate bottom metal for the Howa 6.5 Grendel by Jefferson Outdoors and Oregon gun smithing.
I dont know if there is an internal mag with bottom metal and flush fitting floor plate for a Savage action.

Looks like two of the three Savage 6 ARC are in stock and hard to say when the Tactical will be back in stock.
