Fan Fusion: Pearl x Peridot

Now that our lovable small dot is a Crystal Gem, it won't be long till we see her fusions with the others. With hiatus in full swing (again), I've been madly speculating what their appearances and personalities would be.  This is the first of the three I started with.
For Pearl and Peridot, I believe their fusion would be an unparalleled genius, proficient in both Earth and Gem technology, able to create tech that has the best of both worlds. However, with a cold and indifferent personality, she'd be completely obsessed in research and experiments. Having a super-inflated ego, she'd talk down to others, but would still act kindly towards Steven. Because of this, I believe she'll be on the opposite side of the extreme to Sugilite. While one is maliciously chaotic and impulsive, the other is controlling and calculated.
