There should be no need to outlaw anything if the rule makers use their heads. The 2.4 will be like General Douglas MacArthur's old soldiers they will simply fade away due to attrition and lack of available good replacement engines.
We aren't in the 1950's or 1990's anymore. Junk yards are no longer, they have been replaced by Recycler's like Pull A Part. The car comes in one day the fluids are drained, the car sets on the lot for a month or two or until the most popular parts are removed, then the car is removed and shredded down to be re used again. The newer bigger yards actually have foundry's on site that are capable of melting down entire blocks or cylinder heads leaving behind the steal and other parts and the melted aluminum is cast into ingots before they ever leave the yard (That would be your 2.4 engine).
My statement is simply do not expect things to stay the same like they always did in the past. We have moved away from that way of doing business. Racers are going to have to either change as the economy changes or relegate themselves to racing very limited production and very expensive racing engines.
Better start working on how to restrict and check that boost pressure on the race cars.
