A couple of things to consider,
first is the amount of "pull" you get firing .45ACP loads from a heavy gun such as the Redhawk. The usual ACP taper crimp will almost certainly be enough.
How much crimp you need depends on the amount of bullet pull during recoil, and that varies with how much recoil the load produces, and that varies with the weight of the revolver.
For example, I have done a little experimenting and discovered that there are .38 Special loads that I can shoot uncrimped in a S&W M28 without any bullet jump, and the same ammo in a Model 19 the bullets edge forward slightly.
Bigger bores's heavier bullets change the situation slightly, in detail, but the same principle seems to hold true. I'm not talking magnum level recoil here, I'm talking the relatively mild recoil of the .45acp in a magnum "heavy" revolver.
I shoot ACP from a Ruger Blackhawk, and the recoil is "light" compared to my .45 Colt loads. In the heavier Redhawk, the recoil would be even less, so the force "yanking" the case off the bullet would be less, and I expect within the ACP's taper crimp's ability to handle.
Second, there were ACP seating dies that applied a roll crimp. You need to look at die sets made back in the 70s or earlier, but they used to come that way, for use with the .45 Auto Rim.
ACP cases CAN be roll crimped and still work in some semi autos. You just "kiss" the case with the crimp shoulder in the die. It's not much, but its enough to remove the flare and keep the bullet where it should be during feeding. Keep in mind that this was done back when the Colt Govt model was the only .45ACP semi auto common.
If the regular taper crimp works to keep the slugs in place in your revolver, there is no point to roll crimping the ACP.
It's simple enough to check. Check round #6 in the cylinder for length (baseline) then just shoot 5 rounds, and check it again. If they bullet didn't move, you're good. If it does move, then you have to decide whether to apply a little more crimp and retest, or if you can live with it. If it has "jumped" only a small amount, that's one thing, if its almost out of the cylinder that's something else.
IF, for some reason you need to apply a solid roll crimp to a .45acp (and you are using a bullet made for that, something you can do in revolvers), there is a way. Find a used .45 Colt seater die (roll crimp), take it to your local machinist and have them cut the bottom off, enough so the acp case reaches the crimp shoulder.
