James Loney brings that list way down, but those are elite level OPS's outside of him. The defensive ability of those players vary but ultimately their offense is what carries them. If Wallace puts up a .875-.900 OPS, then sure I would be fine with him at 1B even if his defense is average or slightly better.
Will he be that type of 1B though? Time will tell. His 2009 season as a whole was a bit disappointing. Of course he will be 23 for almost all of the 2010 season so there is time for his stock to rise again. I just feel a bit uneasy about the majority of his value being on his bat, because if he doesn't hit, he's really not good at anything else.
I don't think that his season was disappointing in the slightest; he moved up prospect lists as the year progressed (from 40th in BA's pre-season rankings to the low-20s mid-season), and a .293/.367/.455 line, most of that in AAA in his first full year as a pro, is pretty impressive. Sickels rated him as an A- prospect entering the year, and I'm pretty confident that he'll get the same rating this time around as well.
Can he reach an OPS in the high-.800s/low-.900s? I think so...given his ability to hit for average, and his patience at the plate, it'll likely take something like .190-.200 iso power number to get him to the low end of your range, and that's not an extreme number...hell, Robinson Cano put that up last year (both home and away, so it's not just New Yankee).
