I get it - you want to use something you are familiar with and comfortable with and you are not afraid of designing a board for this.  It will be interesting to see how that set of parts gets mounted on the telescope mount.

Ali Express has the TMC5160s listed at $30 for 2 of them (link below). 

Let us know how that other combination works for you - it never hurts to have another option.
