Reason you won't find a CIS from MIS that handles any multifunctionals is for a couple of reasons.
- They have limited resources and multifunctionals are low use so they just don't test on them.
- MIS would never create a CIS they hadn't tested properly
- Multifunctionals are also a LOT harder to install CIS's into
In a nutshell they know that support required is a lot greater and the potential profit is just not worth it... Personally I don't blame them.. Other CIS kit manufacturers who will claim to support the model have virtually no support worth speaking about and just shove the model in because yes it'll fit but no they don't tell you how to do it.
Best I can offer at this point is that you could request a CIS for a compatible model from MIS or another reputable company and ensure they understand that you need more than just the usual amount of tubing (MIS have a habit of cutting their tubing VERY close to the minimum required) and then taking a long hard look at how you can successfully install a CIS in your printer.
I know I've managed to do it in a CX6600 which is similar but not 100% the same and trust me it was a lot easier than the Canon MP models which are a nightmare so it is possible..
