That's a good idea! Plus, Seachem's site says:
"Flourish Excel™ also has iron reducing properties which promote the ferrous state of iron (Fe+2), which is more easily utilized by plants than ferric iron (Fe+3)."
So there might be some nifty synergistic effects.

TheKrib has a page on
Iron Gluconate too. Plenty of info, but no mention whether it's photosensitive or not.
