I understand. If you want to try using new verbs, then I recommend that you first read lots of example sentences in dictionaries and sentence databases like fraze.it Note how the verb is used in context and also the syntax of the sentence including related verbs, prepositions, and objects. Then you will have a better idea if you can use this verb in the same way as in Spanish, and if not, how you can actually use it. In my experience, efforts to sound more sophisticated often result in a mess and I am guilty of doing this in Italian.

No, "accomplish do" is not used at all. However, for example: " I could help you do your homework." is correct. Often "to do" and " to accomplish" are interchangeable, but "to accomplish" is more like "lograr'' or ''realizar''. I hope that makes sense. :-)
