help needed building a mount to hold cell phone or garmin catalyst

I need some help.  I want to create a mounting solution that can easily swap between my mag safe phone charger and a garmin catalyst.  

Here are the details:
car = c6 corvette

goals: create a mounting solution that allows me to securly mount my cell phone and then remove the mag safe mount and install the Garmin Catalyst for track days.  

Here is what I have purchased so far.

Proclip C6 mount:

Proclip/Scosche MagicMount:

Finally, I purchased a garmin catalyst which uses the standard 1" ram mount setup.  The Scosche setup uses a ball and socket setup but based on some research (I haven't measured yet) uses a 19/32" mount which is 1/32" of an inch larger than the RAM Mount A size mount (9/16")

so far I have had two ideas:

1. build up the 19/32" ball so that it equals a 1" size and then mount a Ram size B ball to the proclip and use a short socket for the phone and an appropriate sized one to position the Garmin mount.  I figured I could do it either with electrical tape or see if somebody who could help me design something that could be 3d printed (thinking two parts that have an ID of 19/32" and an OD of 1")

2. find a RAM mount that adapts a B size to a size, still use the B size on the proclip ensuring I have sufficient support for the garmin.  

thoughts, suggestions, dumb idea and not worth it? 

Bump for a new week. 

The RAM arms should have enough play to grab the slightly differently sized ball. I wouldn't start modifying stuff until you just see if a straight mix and match will work.

yeah but I can't find a RAM arm that holds an A size ball on one side and a B on the other...  So i can get an a size with a AMP plate and a b size with a plate and screw them together but that feels very clugy.  

Got a picture of everything you're trying to mount?  I'll be honest, I know nothing of how a phone is held onto the mount in your car, or the mount you posted a picture of.  But there's probably a good application for some slick design work and a 3d printer.

Same, I'd be available to help design and 3D print something but I'm not sure exactly what you need.

Also, if printing is an option, there's a nice mount design out there that puts the device up higher than the Proclip, in the driver's field of view: https://www.thingiverse.com/thing:5141438
