Rear master cylinder swap

[colingrigson]

I'd like to change out my rear brake master cylinder for one that has an integral reservoir. I'm not a fan of the remote reservoir.
Has anyone done this? Are there any other bikes master cylinders that are a direct bolt on replacement?

Honda CR later years are a direct swap, but I'm pretty certain they're also a remote res. I'm interested to hear of any integrated reservoir versions, but the remote res setup will likely be lighter weight.
