Consider using partimage, at least for NTFS formatted devices. Since 
your storage volumes are heterogeneous, I would suggest making a 
separate image of each volume, this would allow the backup utility to 
figure out the FS type and make the corresponding optimizations.
Your restore script would need to partition the physical device, create 
the LVM structure, and then restore each image on it's place.

Can't think of any, that could handle well the mix of different type of 
FS, specially if they lay over LVM. A home-made wrapper that could 
handle each image separately does not seems to be too complex, unless 
you are looking for something "really abstract and flexible".
Don't forget to consider the cost of the storage media, needed to handle 
simple dd+gz dumps, against the cost of time and dedication to create 
the wrapper. I can't say which will come out a better option, but it's 
definitely something worth to evaluate.
