I bit the bullet and had some professionals do it. They were worth every penny. They used a table saw with a 12 inch blade (mine is 10) and tapered two board widths. You can't tell there was difference in height even when you know where to look. They also didn't use any of the transition stips we had purchased for the doorways . He told me it is a lot easier for him to use them but they look terrible so he took the time to make the pieces fit over the carpet and taper onto the ceramic bathroom floor. Just awsome !!! I'll post some picks plus it was through direct buy and we got a discount on the cost per sqft.
