Kakashi attempted to infuse his lightning chakra into rasengan but failed, which shows that it's possible, also Naruto infused ransegan with chakra of other tbs so i don't see problem with lightning release rasengan.

On the other side, being prodigy or not, wouldn't it be stupid of Kishi to give Boruto such a jutsu, even Rasengan is too much for a shinobi who just graduated from academy, chidori too, but it's more likely to be one of those than advanced form of rasengan which would be an S rank. Not saying it's imposible but we already had prodigies and geniuses already in series and Boruto would be abouve them all then, lol.
