I've never heard of any such,but who knows ? I guess you could try to get Altman to sell you the ballast/guts of a Sattelite I , but I don't remember all that much about the trouperette optics to know this is a real idea or not........
Huh. Strong Int. must have figgered this out in 1985, as I haven't seen any Super Trouperette's touring the countryside. Granted that was 400w HTI (VL1 lamp), but close to HMI.
