Depending on budget I can mention a number of alternatives.
Check out the Motorola Canopy - or perhaps a Tranzeo unit.
Low cost - and you can push 110mb plus over these units depending on
what one you get.
I like the Moto units because they are not the normal 802.11..x stuff

However, the max bandwidth of one WiFi link like that is about 10
mbps.
To increase the total bandwidth, we want to add another antenna in
Building 1.
I don't know the layout of the buildings, but have you considered
using point-to-point laser links between the buildings? I was
involved in a project at a site earlier this year that was happily
getting 100mbps between buildings using roof-mounted lasers.
Much lower latency than 802.11a/b/g as well (assuming that's what
you're using).
If you do stick with WiFi, I'd not worry too much about the downtime
- a) it should only be a few minutes, and b) it can probably be
managed such that it's done during off peak hours.
Can you give us any more information about the WiFi hardware at each
end? I'm not sure simple port trunking on the switches (which is
what I guess you're suggesting in the first approach) is going to do
the job if the WiFi devices are essentially standard APs, since I
presume they'd have their own IP addresses?
If the WiFi devices were operating at a lower level than IP, it'd
probably work, possibly if they were using some sort of L2TP
tunnelling internally? (though you might then have to consider
packet fragmentation, depending on the packet size)
