So you made this class with specific intent to take the speed of thought feat? Or is it just circumstance? If its that important to you, why not just take wild talent with your normal feats, or get a psionic race to start? Considering the multitude of sources of magical abilities, what does this class get from being tied to psionics? Aside from mentioning the display (which seems like its mostly a flavor addition, plus possibly a means of identification), I'm not sure that this has any need to be tied to psionics.
