Not that I know of
I guess they don't want to have serious "romantic" implications or whathaveyou in the anime, but they still have light romance plots every so often. I feel Tact could be a good stand in for a side character that viewers wouldn't get too upset at, but they tend to always use joke characters instead. Like the romance plots tend to use a younger Volcott, NORMAD, a rice cooker, either of the two young boys they randomly introduced as rivals, etc. But why use them when you have Tact?
Earlier Galaxy Angel episodes attempt to follow a plot and lore structure but the later ones lean heavily into parodies or absurdity with the characters fulfilling certain rolls without any continuity. I think Tact would be fine for this.
Like if you take the last special Episode 19 of Galaxy Angel Z/Season 2 where Forte meets up with an "old friend" for one last dangerous mission, which is like some brown hair guy who never shows his face, I think if they used Tact there instead the episode would be better off. They can do the same thing where they don't show his face, but viewers could tell by his blue hair and voice actor. And then just recycle him because they recycle side characters all the time elsewhere.
