I don't think a remake would ever happen really. Original BSG had a concept but not much in the way of overall plot. B5 was very tightly plotted with a beginning, middle, and end. Realisitcally, we'd have to wait another 20 years before they'd even consider a re-make of B5. I'd rather they but the bullet, gave us the Telepath War and finished it up for good. All the nibbling around the edges with mediocre stories has diluted the franchise sadly.
Actually, I wish they'd re-make Day of the Dead into a double episode and feature a few more characters. I'd quite like to see Ivanova and Marcus meet up!
