I’m curious if you’d be able to remove the GMT parts off this movement and mount them on the high beat 4813? They aren’t that expensive on the fleabay:

Might not be possible bro. The topside of the DG5833 mainplate has a unique configuration to accommodate the extra GMT wheel gear and the extra setting wheels. These are pre-molded posts on the mainplate to set these gears on that would not be present on the DG4813 non-GMT movement.
High beat needs a different escape wheel, pallet fork and balance assembly which likely means a slightly different configuration on the bottom of the mainplate. So combining the different needs of the top and bottom of the mainplate may not be feasible.
Not to mention the huge PITA of resetting the train wheels and bridge on a DG movement. IDK any watchmakers, even very experienced ones who like working on DGs. Even snapping a second hand pinion (which is not uncommon) often means just replacing the movement. It's just not worth the aggravation to take it apart and replace a center wheel. Someone might want to try this, I don't think it will be me.
