All of the metal-framed CZs share the same basic grip design, although the grip on the compact (and sub-compact models) are less long through the grip area (i.e., they use shorter magazines.)
Note: some of the full-size CZs have a different trigger shape, and that may make trigger reach a little different. I've not owned an SP-01, but suspect it has a different trigger than the P-01. That will make the grip of the SP-01 feel a bit different than the P-01, although the grip itself is almost identical. The trigger CAN be changed by the owner.
The SP-01 isn't really a larger version of the P-01, it's actually an improved version of the 75B with some P-01-like features designed for gun-game competition. There have been two or three versions of the SP-01, including a steel-framed P-01 and a polymer framed version called the P-01 Phantom; some were available with safeties and some with decocker.
I thought the Phantom had been discontinued, but the CZ USA website (updated for 2017) shows ONLY the polymer-framed Phantom, and a Shadow 2 (which is like an upscale SP-01). None of the more traditional 75B models are shown, and the current CZ-USA website doesn't even show the stainless steel models or the compact models. I suspect that site is a work in process, still being updated.
You should be able to find a used SP-01, or check with the CZ Custom Shop about whether they can get you an SP-01. (CZ also makes a SA version of the 75B, as well as stainless steel versions of the traditional 75b, but with ambidextrous safeties. Except for the Phantom, all full-size 75Bs have steel frames, while the P-01 is alloy; the SP-01 will be a LOT heavier than the P-01 -- but that makes recoil less noticeable.)
You might want to look at the CZ P-07, or P-09, while you're at it. Similar, but not exactly the same grip. I've had a lot of CZs over the years, and still have an 85 Combat, along with several CZ-pattern guns (called "clones", but they aren't clones). I also have a P-07, which I like a lot -- and prefer it to the alloy or steel CZ compacts.
