Psicrystals (Expanded Psionics Handbook) are manifestations of the Psion's consciousness on the physical plane, with the power to manifest ectoplasmic legs to move and climb. Ectopic form (Complete Psionics) allows you to create astral constructs with distinct appearances and specialties.
While it is clear if you did this you would only get to apply one shape to your psi crystal, I was wondering if the rules as written allow for the rules as interpreted to let something like this happen, as a variant of the Elemental Envoy and Improved Psicrystal (feat) themes.
I normally wouldn't ask a question like this, but it seems to me that Astral Constructs and Psi Crystals are both constructed in similar ways, with the exception that Astral Constructs are Temporary. So I figured if a psion can construct both, can they apply a "during construction modifier" to both, even though they are clearly trying to focus on Astral Constructs, I'm wondering if the Psicrystal can be ruled similar enough to receive a similar flavor text advantage?
additional information: The side effect of doing this to your Psicrystal is that it would resemble a crystalline familiar, like a snake, spider, or bird, instead of a faceted gemstone.
