What you are describing is possible the questions are whether it wold be effective and would the scars ben a good tradeoff. It is never wise to make the assumption that a brow lift will get rid of forehead wrinkles as those effects are usually very limited. Also the shorter the scar (like limited to between the eyebrows) will also make for a very limited brow lift effect. The length of a hairline browlift procedure has a bearing on how much brow lifting effect can be achieved.
If you could be certain you will not continue to have a higher hairline
you could consider what you have mentioned so your scars will never show. Otherwise you would be better off with an endoscopic browlift and if you didn't want something that complicated, you could choose to have the scar just above your brow in one of your forehead furrows... but it takes a while for the redness to go away.
Forehead Lift with Short Pretrichial Incision and Lateral Direct Brow Lift
You can demonstrate the effectiveness of a short pretrichial incision by placing your fingers at the hairline and lifting up. I think you'll find that limited elevation can be achieved if that incision is limited. A direct brow lift can be done laterally but there is the possible risk of an unfavorable visible scar. Hair will grow through a trichophytic incision across your entire hairline so the entire incision will be hidden. I suggest you consult with a surgeon experienced in this work who uses all brow lift techniques to discuss your options.
When performing a short scar, there is minimal to no skin to be removed due to the excess bunching of residual skin. The a coronal approach allows a variable amount of skin performed to lift the forehead and anchor it, in addition to softening the frontalis and corrugator muscles and placement of fascia grafts underneath the vertical lines between the eyebrows. The reason for the pre-trichial approach is to lower the hairline, not raise it. For more information and many examples of browlift, placed in the link and the video below
Your plan seems feasible. You need to find a doctor who has experience with this exact plan. Most of us would recommend whatever has been working well in the past such as a trichophytic hairline aporoach or the endoscopic one.
You have plenty of hair, so might want to consider an endoscopic lift. This will give you a more even browlift, getting the medial and lateral brow. It will move your hairline back a little, but usually not much at all. If you try to elevate just the medial brow you may get an odd shape to it, and look surprised.
