If you can settle for MX-style switches that have a very satisfying click, then I'd like to point you to Kailh Box switches. There's a bunch of variations, but Box Jade or Pink (from NovelKeys) have been my favorites.
The tactility is very well defined, and the tactile mechanism (click bar) is IMO better than Cherry-style click jackets, like seen in Cherry Blues.
A split keeb with a white backlight that accepts MX-footprint switches should be simple to find.
And if you fancy getting more 'Boutique' there's always the ZealPC "Clickiez" which are a reinvention of the ALPS style of click mechanism in an MX compatible chassis. Fabulous (but expensive) switches.
