You could use your high-res bump map to influence the diffuse values by using a color mix node to get a more detailed diffuse texture. If you haven't already done, I highly recommend reading
http://www.makehumancommunity.org/forum/viewtopic.php?f=2&t=15545. The tricks Mindfront does with procedural skin cells should also work with your bump map.
The SSS is too high. I basically set it by looking at the ears and tip of the nose but its probably too high in those areas too. I plan on painting a map to change the levels of SSS but that is still in future plans. I probably should have posted this in WIP.
I am manually painting the bump map. I am using texture paint in blender. I started by creating a 50% grey texture, RGB (0.5, 0.5, 0.5), then painting with alpha textures. I am using the anchor mode under the stroke setting. This allows the brush to be resized and rotated with every stroke which is very useful! I tried using a tablet to paint but it did not work well for the bump map. In order to see what I am doing I work in material mode and plug the image texture, that I am painting, into the normal input of a glossy shader and then to the material output. I'll post the tutorial where I saw the set up. He as a few tutorials on skin texturing but this tutorial is the nuts and bolts. His channel has some good stuff on it.
https://www.youtube.com/watch?v=fZyRimOBU-gI have been reading through Mindfront's post. It is amazing stuff. There is a ton of good information and I am learning quite a bit from it. I am definitely going to use a lot from it. I would like to be able to blend multiple bump map and I think the procedural texture you posted may be where I start. There is a lot to learn from your procedural skin post too. I am still behind the learning curve with the node setups but I am trying to catch up.
