analyze jazz chord progress



Hi, there,
How do you analyze this chord pregresses into (functional) Roman numerals?

Gm7 - Bflat m7 - Am7 - Cm7 - F7 (#5 #9) ||
Ema7 - Dm7 - G7 - Cma7 - Bflat m7 - Eflat7 - Dma7 - Cma7 - Bflat ma7 -
Aflat13 (#11) ||
(for clarity, sharp is #, flat is flat)

If, take the key as Gm, I suppose part of the first verse as
Gm7 (i) - Bflat m7 (iii) - Am7 (ii) - Cm7 (iv) - F7 (#5 #9) ||

and perhaps part of second verse as
Ema7 - Dm7 (ii) - G7 (V) - Cma7 (I) - Bflat m7 - Eflat7 - Dma7 - Cma7 -
Bflat ma7 - Aflat13 (#11) ||


How do you think?
Thank you very much ^_^
