Well not exactly hacked per se, but I found you can manually edit one of the MSKLC source files to remap CAPSLOCK, and I assume any key for that matter. And please forgive me if this is old news for I searched and could not find this info anywhere.
Mandatory stupid warning: I assume no responsibility if this FUBARs your computer. I have tested it on mine (Win7 32 and 64 bit) and it seems to work fine but use at your own risk.
Instructions:
(1) Download and install Microsoft keyboard Layout Creator 1.4 (MSKLC) from Microsofts website.
(2) Copy a backup of the file C:\Program Files\Microsoft Keyboard Layout Creator 1.4\inc\kbd.h
In 64bit windows its: C:\Program Files (x86)\Microsoft Keyboard Layout Creator 1.4\inc\kbd.h
Keep this backup in a safe place so you can easily restore the file if need be.
(3) Open (EDIT) kbd.h in notepad. Scroll down till you see the keyboard type 4 definitions.
Should look like this:
#if (KBD_TYPE <= 6)
/***************************************************************************\
* T** - Values for ausVK[] (Virtual Scan Code to Virtual Key conversion)
*
* These values are for Scancode Set 3 and the USA.
* Other languages substitute their own values where required (files kbd**.h)
*
* Six sets of keyboards are supported, according to KBD_TYPE:
*
* KBD_TYPE Keyboard (examples)
* ======== =======================================================
* 1 AT&T '301' & '302'; Olivetti 83-key; PC-XT 84-key; etc.
* 2 Olivetti M24 102-key
* 3 HP Vectra (DIN); Olivetti 86-key; etc.
* 4 * Enhanced 101/102-key; Olivetti A; etc.
* 5 Nokia (Ericsson) type 5 (1050, etc.)
* 6 Nokia (Ericsson) type 6 (9140)
*
* * If KBD_TYPE is not defined, the default is type 4.
*
* KB3270 comments refers to KB 3270 keyboards in native emulation mode (DIP
* switches all OFF), and the Scancode Map used to convert its scancodes to
* standard scancode set 1.
* KB3270 <= 57 - this entry is reached by mapping from scancode 0x57
* to an arbitrary scancode: the VK is what counts
* KB3270 => HOME - this scancode is mapped to the scancode for VK_HOME
* KB3270 - no mapping involved, a scancode for KB3270 only
*
* _EQ() : all keyboard types have the same virtual key for this scancode
* _NE() : different virtual keys for this scancode, depending on kbd type
*
* +------+ +--------+--------+--------+--------+--------+--------+
* | Scan | | kbd | kbd | kbd | kbd | kbd | kbd |
* | code | | type 1 | type 2 | type 3 | type 4 | type 5 | type 6 |

Save the file. And now 'copy and replace' it back into the %MSKLC%\inc directory so MSKLC will now use the new definition when it runs.
(4) Run MSKLC as you normally would. Create or import a layout and then "build DLL and Setup Package".
Viola! The resulting *.DLL files will have the remapped CAPSLOCK. No need to mess with registry, and you don't need to reboot to get the original QWERTY + CAPSLOCK behavior back. Just change to a normal layout with the language bar.
You can also put CAPSLOCK on the BACKSPACE key and swap LSHIFT/RSHIFT with letter keys. That is all I have tested so far and it all seems to work fine.
