I think the clearances on the miter saws would interfere with larger timber, movement to and alignment with heavy timber to a dedicated mitersaw station requires a special dance, accuracy would be limited by the blade not being regulated by the table or fence, particularly for depth of cut and the variety of cuts would be limited. I would prefer hand held circular saws with robust bases. I have not used a Makita planer but will recommend either Mafell or Protool-Holzher, despite major sticker shock.
