War matching: hourly/every other hour batching for even match-ups?

Like many groups, we've let the war search run 30+, 45+ mins only to be eventually matched with a much higher th opponent clan. We learned to cancel/restart every 10m, but after a long period of this sometimes we simply have to let it run.

Would it be possible for SC to collect war requests, and at the end of every hour or two, match all the collected requests? This batching should provide better liquidity for matches, and anyone not receiving a match could get priority matching next round (if implementable).

Ive seen the 23 hr war prep suggestion to accommodate the long searches, so people seem ok with the lag or wait time, especially if it ensures a more even match up. Perhaps SC could even allow clans to designate a start time, submit war request, and provide even more notice. There's a 4-6hr start window that would work perfectly for us, although some may be more limited.

I realize there are several suggestions here, but wars are a huge part of the game for many and getting paired as a primarily th9 clan against a primarily th10 clan with infernos just isn't fun. Getting paired against same/very similar # of th9s is awesome--certainly the highlight for us in playing coc!
