After the first D&D Next playtest came out (and my son absolutely loved it compared to 4e since it moved so much faster) my group made a few changes to 4e similar to what you've done.
- Cut monster hp to 33%
- Introduced a "veteran" monster between standard and Elites that had normal HP, these were worth 50% more XP
- Cut PC surges by 1/3, round up
- Eliminated action points
We played through Thunderspire Labyrinth using these rules and it worked great. Things moved much much faster and felt a lot more "old-school". Players no longer felt the need to maximize the use of encounter powers and instead defaulted to basic/at-will attacks in the opening round to scout out the enemy.
