That's a really practical question that many engineers face when dealing with mixed vendor systems! The short answer is yes, you can mix Siemens PLCs with Mitsubishi servo drives, but it definitely comes with some challenges that could turn into a maintenance headache if not handled properly.

From what I've found, the integration is possible through gateway devices that bridge the communication protocols - like CC-Link IE to Profinet converters. These act as translators between Siemens' Profinet and Mitsubishi's native protocols. However, this adds complexity to your system with extra hardware and potential points of failure.

The real maintenance challenges come from troubleshooting. When something goes wrong, you'll need expertise in both Siemens and Mitsubishi systems, and you'll likely face the classic "finger-pointing" scenario where each vendor blames the other's equipment. Support becomes more complicated since you're dealing with two different technical support teams who may not be familiar with the other vendor's equipment.

If you do go this route, make sure you have documentation that clearly maps out the communication pathways and have team members trained on both platforms. But honestly, if you can stick with one vendor ecosystem for motion control, you'll probably save yourself a lot of headaches down the road!
