Yep, keeping the same meaning, keeping the right number of syllables and maybe keep some ending rhyme might be tricky. Or it could just amazingly workout rather easily, you never know.
I see there's no need to reinvent the wheel. I found an instrumental of Soar on Wings Like an Eagle on youtube with english lyrics 'per measure'(
