Well, if they could come up with a reliable plug and carburetor that will work with gasoline, then they may be able to maintain some market share. I mean for .60 size and below in displacement. I am not stuck on using glow fuel, but will always have a desire to run smaller engines. The other issue, is gasoline mixes typically use less oil. But the bigger engines have ball bearing on the con rods etc. So any small gas engine will need rich oil mixes.
