Whether or not (and how much) you like Motorhead is irrelevant to the point you were trying to make, which applies to tributes generally. And really to Baz's as well, though he didn't write it out proper longform. I'm sure there was was no malice in it; it was more like wait for the rest of the gang to vote, it's only been two.
Personally, I say do it... eventually. It is too soon right now (but not to soon to start putting it together and jamming). You've got a year to get the right guys, jam it out, pick the rights songs, and get solid on those. Book the venue well in advance to make sure you get the best date. Other people in your area will think to do this on the first anniversary (or his birthday; not that I know when that is) too, but likely not be as prepared. You have the advantage on venue, date, promotion and lineup.
I'm with nofi that I generally don't feel tribute bands as much. One cool thing a local promoter would do is to have a whole pile of bands not all to similar do 3 songs each; quick change on a shared backline. That way you get a lot of different interpretations of the band's music and it's more interesting to me, both as spectator and participant. But that's just me.
