Can You Make a "Hyper Form"?

[Trusk'our he/him]

If a singer were give another Gemheart or a bigger Gemheart via Hemalurgy, could they get a Form that was more powerful and more pronounced?

For example, if a singer gained a second Gemheart and then bonded two painspren to gain Warform, would they be extra strong and muscular?

IIRC there was a WoB where Brando said that if a knight radiant bonds two spren of the same order, that would not increase his power.

Naturally, the Nahel bond is not quite the same as the bond between a singer and their form-granting spren, but that's the only precedent we have, so I would predict (but not very confidently) that a singer with two bonded painspren would have normal warform.

 The forms are determined by the type of spren more than any characteristic of the gemheart we know of (and the Singer gemhearts seem to be more universal than others).  As far as we know only time two spren have "shared" a single gem or gemheart is when Timbre trapped the regal voidspren, and they were using separate Bonds to Venli to make it all happen in more of a two-system hack. 

A "Double" gemheart might be possible with Hemalurgy but if we look at sensory stealing it just makes what they have better rather than growing additional organs so I think a bigger gemheart is more likely.  That might allow an entirely new spren that previously wouldn't fit and so a previously unseen Form, but I dont think it would let two spren share a single gem.  A hemalurgic double Gemheart would be "unnatural" enough that could have all kinds of unforeseen circumstances, from Koloss-like superforms to something even more horrific and a lot less functional.  The saving grace is that the spren involved would have to be willing (though not sapient) so a Form-based change wouldnt have to be permanent.
