There isn't even any real research that needs to be done he just needs a gene template. Or Silver Surfer could do the same any time he's had a disagreement with his bosses policy. Cosmic Awareness copy Franklin's genetic structure or Legion or Mad Jim Jaspers or if he really wanted to go all out copy Protégé from earth 691. I'd like to think that there is some kind of cosmic restriction against nonsense like that.
In theory he should be able to do any and all of that. No explicit limit has been shown to his basic ability to alter and augment his physiology - I mean he's the bloomin' snow in Namor's mouth! - and to absorb ever greater levels of power.
If we take Galactus at his word, then Surfer's channelling of The Crunch Energies was a feat beyond Galactus' himself ... But even if not, it clearly represents an ability to deal with energies beyond the scope that Proemial Gods could cope with - gods who themselves challenged Galactus.
The simple and obvious truth is that Surfer is writer/editor limited.
That The High Evolutionary only becomes as powerful as his story demands, having gone from a regular genius-level human to somewhere in the trans category.
That Thanos, who himself has augmented his body beyond his Eternal physiology, has not become a peer of Galactus by augmentation alone, just because that isn't a story Marvel wish to tell.
We can prove that Surfer can absorb energies sufficient to kick an _amped_ Watcher's arse. That he can absorb biological and spiritual energies (souls), and amp from them significantly.
We also know that Korvac basically made himself Skyfather+ just simply by absorbing the Power Cosmic and the knowledge of Galactus' ship.
So that kind of amp is definitely possible, in comics.
