Of course, you cannot rewire an organisms because of all the dependencies (although many evolutionists think this is very simple, e.g. from a ametabolous insect to a holo - or hemimetabolous insect).
The EcR isoforms were newly identified in 51 species of insects and non-insect arthropods, including direct-developing ametabolous and hemimetabolous insects.
Thus, intensive costly food provisioning of their young is not necessary, especially as young instars are rather independent due to their hemimetabolous development.
