No, it's not worthy to me because TXST and UTSA are not even in the same conference. Both conferences are at the bottom out of all conferences, but Sunbelt is dead last.

Only one team will benefit from the win. If UIW had a rivalry with TXST, TXST will most likely win every time which does nothing for them. But at some point if UIW wins, it makes TXST look bad and UIW gets hyped up.
Same thing if UTSA has a Rivalry with Houston. Houston most likely would have won this year and if that was the case, then it would mean nothing to them but a W and maybe a bit of revenge. But the year UTSA beat them, UTSA was over hyped and didn't do much that season while UH looked bad that game but went in to have a winning season.
So now if UTSA beats TXST it won't really mean anything because it doesn't count as a conference W and it doesn't count for anything beating a dead last team in a dead last conference. Now if TXST wins, their fans will start talking about how they will win conference this year but still end up with a losing season. We already started to see a little bit of that after close margin App game.
Cross conference rivalries are just not my ideal rivalry. I'd prefer UNT, UTEP, or la tech over TXST. At least a W would get us closer to a division win and thus means more to the team instead of an OOC bottom 25 win.
