If you replace the Teensy 4.x it would have to be something very close to the same pinout, foot print, cost and features otherwise it would just be a new product. Ideally you would find a way to source the Teensy directly bypassing Sparkfun.

sparkfun is the single source supplier (and now maker of the product).

  Spinning an IMXRT1062/IMXRT1064 design sans the terrible Teensy bootloader should take a day or two at most. These chips have perfectly-fine ROM USB bootloaders and SWD, don't ruin them by adding extra garbage.

    The layout of the Teensy 4.x was challenging as I recall with the speeds involved. But maybe you are a demigod of compact high clock designs.

      Nothing on that board is remotely high speed or challenging. USB HS on a board that small is a non issue: it's one measly differential pair with easy impedance requirements.

        Go ahead and make one then, we'll be thankful.

  Yes, obviously, but they don't make the chips, so can't you just source the exact same chip, make thing pin compatible and call it a day? Then you'd have a drop in replacement, any changes you make will cause disruption for people downstream. https://www.nxp.com/part/MIMXRT1062DVL6A https://www.nxp.com/part/MIMXRT1062DVL6A
