To a certain extent, yes. And with a doubled-up X-Axis, you should be OK (unless you’re trying to build a 6’ wide gantry). The killer may be the mounting plate. You’ll need that to be stiff enough not to flex.
As far as the steppers go, the “stock” NEMA-17’s @87oz-in should be plenty. Any more power means you’ll want more speed and/or DOC, neither of which are terribly conducive to the LR2 design. Remember, this is still an entry-level, hobby CNC.
One thing to think about is to add some rails on the inside of your wheels to help the gantry stay square. Just be sure that the rails are square, because your rig is only as square as the rails…
