You've probably seen these links but they are here for others as they are usefull especially the eyepiece specification table.
I believe you are still after a minimalist set of eyepieces to use standalone and with your 4x Powermate and Baader coma corrector. I have zero experience with the Baader coma corrector so cannot comment on it and its suitability with the Powermate. To make your minimalist set work you would also need a 2x Powermate (comes in 2" only) and then complement with all the 2" eyepieces with field stops greater than 27mm. This is an expensive and cumbersome route and I am not encouraging it.
You should buy a low power eyepiece for low power wide true field (and wide apparent field if you desire) work. Then buy some mid and higher power eyepieces for other magnifications.
I recommend you set up a spreadsheet in Excel and list all the large 2" eyepiece focal lengths in the first column. Then in the second column divide each in the first by 2 (shows effect of 2x Powermate). Then in the third column divide each in the first by 4 (shows effect of 4x Powermate).
These will be your effective focal lengths. (Without any amplifying effects of a Paracorr - 1.15x). Not sure if Baader coma corrector is a non-amplifying type.
You could end up buying all the low power options just to get some mid to high power options with the Powermates. If sticking with 4x Powermate only then you jump from low to high power with just about any eyepiece you choose, 21 Ethos, 22 Nagler, 27 Panoptic, 31 Nagler, 35 Panoptic, 41 Panoptic, 55 Plossl, i.e. no mid power options with 4x only.
I do not recommend achieving high power in this way not because of any optical reason, in fact the views are going to be first class, but because overall cost will be greater than if you simply bought a low power, mid power and a couple of high power eyepieces. Also too your optical train sticking out of the focuser will be long and heavy if using the Powermate, coma corrector and large eyepiece together and will likely lead to balance issues depending on viewing angle.
