Why would it be difficult to obtain a Heter Meah Rabbonim? It doesnt say anywhere it has to be big rabbonim. You can get a 100 kollel guys with smicha. Nothing would make it halachicly any less valid as a result. (And it is only needed as a result of a cheirim/takana/minhag that even not all sectors of klal yisroel was mekabel in the first place that would necessitate the Heter altogether.) Why would you think otherwise?
