You can't make neutral/cool Ilford MGIV look warm.

LPD fully develops prints in 120s unlike 130 diluted 1:3 or higher.
The extreme cold-tone end would be undiluted as opposed to 1:1.

Even with MGIV, the difference between 1:0, 1:1, and 1:2, is noticeable from cold blue blacks to mildly cool blacks. This is, at least, my experience, which is admittedly only 10 years, and using LPD for only two of them.
