First of all, as far as I understand you can just use some css/javascript 
compressor
and use it instead of ordinary file. And probably specialized compressors would 
do a good job.

Isn't it what HTTP-Keep-Alive and for?

Also HTTP/1.1 allows you to send several requests for different images without
waiting for completion of downloading first one. Isn't it better?

Generally most web servers know to serve
static files a way better than any framework I know for a simple reason - this
is what they are benchmarked against most often. They use best OS API like
sendfile or others to do the job done. I'm not sure how much would it
give you to push such thing in framework, also how exactly can you combine 
serveral
images in single request?
