Frowned upon? My OCI interviewers were interested in my trip. Go for it you aren't likely to get a paying legal job 1L anyway, unless you are at a big school. I did do 6 weeks of volunteer work as an intern for a judge the second half of my summer. Which was actually more impressive to the employers. But don't discount it as a possibility, when else will you have time for something fun like that in that next few years?
