You are welcome! ;-)
Normally even these cheap CSR BC417 (BT module, not BLE) have
Others like Broadcom chips (i.e. used on Wiimote) has a firmware on
ROM but let you to apply patches from an external storage.
In these case you are right, it is not possible/feasible to replace

Yes, it could be possible to run NuttX along with original BT stack.
I know you are a FLOSS guy, I remember you from others mailing list
(OpenOCD, U-Boot, etc), the open source members always meet in either
mailing list! :-D
About the nRF51822, there is a nice breakout board to toy with it:
This chip (nRF51822-QFAB-R7) cost about USD$4.11 at Mouser, for
comparison the Kinetis MKL25Z128VLK4 I'm using in my projects cost
