Well you won't have to download those 5 patches again at least. I have a lot more (11 total) but they stretch back a long time, back to version 2.100 and some of them are more incremental updates.
I'd hope now they'll have fewer updates but they'll be bigger in size obviously, so maybe you'll be OK. What version numbers do they go up to? The latest patch got released on Tuesday and is v.2.602.
The only thing I can suggest is what sr4470 said but don't know if that'll cause some issues.
Otherwise you'll have to download the rest of them if you come back to installing it unfortunately.
