Rob,
If you plan on removing the front mount, none of those items will be a suitable substitute unfortunately.
None of those items are meant to support that kind of load, only to add support to the front mount.
Something you could try is using this kit you suggested:

Then weld it to the frame horns, some modifying would be necessary. Or figure out a way to bolt it to the frame horns and use the included rubber bumpers so that it isn't "solid mounted"
