Not a chance, the 190 was not PowerBook Gray, was not 68030 architecture, had T-REX/IDE/PCMCIA on board and that, by definition, made it the improved BlackBird-> 5300 series progenitor, not a 100 series 'Book.
The 150 is, unarguably, the far bookend of the 100 series, but not the 68k series, as you pointed out. YMMV
