There are several threads here on altitude. While every individual is different, my answer to your question in no, it won't make a bit of difference. In my experience, which includes living at 11.5K for extended periods of time (3months to 15 months in the Andes), only an extended stay at alititude really works. A day here or there won't do much for you.

I've been fine at 7500k for a few days, but on the other hand, many years ago I almost died at 11.5K when I developed HAPE the morning after I got off the plane. Took about a week or so in a clinic before I recovered. Happened twice in two years, as I recall. First time wasn't as bad as the second.

Just monitor yourself, be aware of symptoms and go down if you start feeling bad. That is the only practical cure short of hospitalization or breathing off an oxygen bottle.
