Ahh, thanks Harry. Of course! Straights beginning with cards 6 thru 9 interfere with possible royal draws. So your answer for 7-9 also applies to 6 (who's straights include 10). I should've suspected Bob had an article on it. I'll have to check it out later.
Even if wild royals count as naturals when the wild card is Ten thru
Ace, what I was attempting to point out in my previous post is that
changing the wild card from deuce to any other card has a negative
effect on the EV, often rather significant. For example, per
WinPoker, Sevens Wild using the NSU paytable returns only 97.5%. I
believe that Fives Wild thru Nines Wild would have the same EV, due
to the aforementioned fact that the number of straights/SFs they are
involved in is the same. So only Deuces Wild would return 99.73%;
Threes Wild would be less, Fours Wild even less again, and Five thru
Nine 97.5%. The strategies for each would likely be different, too.
Bottom line: avoid this game, or play at your own risk! 
This game is essentially a subset of "Anything's Wild", in which the
player can select their wild card. As you surmise, a deuce is optimal.
vpFREE FAQ links to a Dancer article that discusses that game, among
others:

My initial gut feeling about the ER of that game would have been
similar to yours - that wild 5-9 would have identical ER's given the
same number of possible straights formed in each case.
However, Dancer's ER table for this game indicates that ER grows
weaker as you progress up in rank from 5. A minute of thought reveals
that this is due to interferences with RF holds. E.g., for suited TJ,
a wild 7-9 reduces the number of staights that might be formed vs. the 6.
My few seconds of thought on this leaves the reduced ER for a 6 wild
vs. 5 a mystery. But, without dwelling on the question, I have to
suspect that this is related to the dual straight role of an Ace. (If
I had access to the game in AC I imagine I might be sufficiently
curious to noodle that one out
