It would be nice to have the option to convert Dspecs to elites.

Cost: (Price of elite) - (Price of Dspec)
Training time: Time of elite

This would allow for instance a Faery who has a bunch of Dspec credits from a war to train up their Dspecs for free, but pay the price difference between the Elite and Dspec. They don't get free elites, but they also don't have to release the Dspecs later and pay for complete retraining.
