I have no idea what the size of the market is, but it must be of some size. It obviously supports the SSTRAN, Rangemaster, Gizmo, Talking Sign, Talking House, Ramsey, etc.
I think a unit that combines the best of the SSTRAN and Rangemaster and sells for an affordable price would be a big hit. You probably would take away business from all parties. If it was type certified and still reasonably priced, you probably would capture the Rangemaster market.
