I completely agree, but unfortunately it's the only one I know of in this format.
I just asked today about the way to do paper wallet for Monero and.. at least you have only to run an exe (no install) and you don't have to download the blockchain.
Maybe this also helps a little. Here's the response I got: https://bitcointalk.org/index.php?topic=583449.msg9855347#msg9855347

The only thing you need is to download the source of https://www.bitaddress.org/ site.

It could be found as a zip archive here: https://github.com/pointbiz/bitaddress.org/releases.

Then find out the address prefix of the coin in question - check the file src/base58.h for PUBKEY_ADDRESS:

Now unzip the https://www.bitaddress.org/ source zip file to some location and open the bitaddress.org.html file with notepad or any other plain text editor.
Find the following line in that file:

As of release 2.8.1 it is line no 4757

Replace the 0x00 in  this line with a value you found in the base58.h (with 63 in example provided)

Then save the file and reopen it with a webrowser.

Enjoy.
