You may, but only if you provide a complete translation in English. The
Forum Etiquette and Posting Guidelines state:
"If your post includes words in tlhIngan Hol, please provide an English translation somewhere within the post unless you are posting in the
"Conversation in tlhIngan Hol only" section. Either line by line or in footnote form is fine for the translations; if you can get creative without getting confusing, so much the better."
Besides, you will reach a much larger audience if you provide an appropriate English tranlation.
Having said that, I look forward to reading your work.
