If the KoboTouchExtended driver has problems converting a epub to kepub on the fly, it is a probably a bug and you should report it in the thread for the KoboTouchExtended driver. For convenience until the bug is fixed, you might want to convert it with Kepubify and import the additional format into the same book in calibre.

When transferring small batches of books (assuming it works), generally the on the fly conversion is pretty fast. However, when transferring large numbers of epubs all at once, it can be time consuming. If you do this often, it might be worth converting a significant number of books to kepub (or maybe just large ones), but otherwise, there's not a lot of point, and it's easier to just let the driver do it on the fly.

Calibre is pretty smart, and when multiple book formats are available, it will choose the best one for the device.
