Whatever you do, I'd recommend keeping it to a 1.045-1.050 starting gravity and pitching 2-3 packs of Saflager 34/70 when the wort is oxygenated and around 50 degrees.
It's a clean, flocculant, non-fussy yeast that is tolerant of primary fermentation temperatures between 45-55. After about 7-8 days at 50*, move the beer to a 60-68* environment for a couple of days(or turn up your ferm fridge), then dial back to your kegerator for 5 days to 32-38*. Then rack to a keg with some gelatin or bottling bucket per your normal routine. 2-4 weeks after packaging you'll have a dyno-mite beverage.
My absolute favorite beer is a simple pre-prohibition pilsner. 90% 6-row or 2-row barley, 10% maize, bittered to 35 IBU with Cluster and finished with Cluster/Saaz for aroma. 34/70, WY2007 or WY2035 are all good choices. Use fairly soft water and mash at 150 for 75 minutes with no mashout. Simple. If you choose 6row, a short protein rest at 130* before the 150* rest is not a bad idea, but not life or death.
