You're right. In fact whenever I look at the JRS FTD in particular, I admire that cover and think how nice it would look on an LP.
It would sound great too!
And vinyl and FTDs being great collectors' items individually, I would imagine that limited edition vinyl pressings of the FTDs would sell handsomely. However, I don't know anything about the cost of pressing records, but I do know it would be a lot more than what it costs to manufacture CDs. Still, I bet people would pay top dollar for the records (they already do for the CDs, I know, but I bet they'd pay more for the LPs).
