7510 thunderbolt 3 upgrade. Is it possible? Need help

So a while back I purchased a 7510 with the following specs: 15.6inch UHD IGZO, Intel Xeon E3-1535M, 32 GB DDR4, 512 GB SSD, Nvidia Quadro M2000M 4GB, NFC smart card, Fingerprint Scanner.

I didn't realize until after it showed up that it lacked the thunderbolt 3 port. Without going into too much detail, I need a thunderbolt 3 connection for a feature film editing project I'm going to be working on in a couple of months so I can attach a raid 5 array for editing footage that cannot go through a usb 3.

I got a great deal (sub $1900) on the computer and I have some spare cash lying around and was wondering if I could install an i7 motherboard, thunderbolt port chassis and left IO board with a thunderbolt 3 port and would those upgrades "work" with the rest of the computer. This would be my first attempt at doing an upgrade of this kind.

I think my options are either sell the comp and get another similar spec model with a thunderbolt 3 port or attempt these upgrades (assuming they are feasible). I'm not confident I could sell it online in time and thought maybe the upgrades would be a better route in case I can sell my used parts.

I really appreciate any help on this.

 

AFAIK While TB3 ports use USB-C connectors and are compatible with USB-C Devices, Most USB-C ports aren't compatible with Thunderbolt 3
(just like how TB1 and 2 use specially marked Mini-DP ports but that doesn't mean all Mini-DP ports support TB1&2 most do not)

 

Are you 100% sure that a UASP-enabled USB 3.0 device cannot deliver? I've got a 480GB Sandisk Extreme USB 3.0 SSD which gives sequential read / write in excess of 360MB/s. Here's a useful comment about TB 3 speed.

Would a second internal SSD be an option? I don't have significant video processing experience but have always considered it better to have a uniform data flow: read from one drive --> process --> write to another drive (or maybe that philosophy, based on mechanical HDDs, no long applies but could well help get best throughput from an external interface).

Alternatively, I'm sure if you spend enough on the right parts then you can get a Thunderbolt-enabled 7510. However, parts tend to be expensive until people are dismantling dead notebooks to sell the working parts as spares.
