I don't. There are some similarities with tryptamines & phenethylamines, eg. alpha-methylation works potentiating and protecting from MAO:s in both. Generally, most things concerning the ethylamine-tail work similarly in both chemical types, but additions on the aromatic ring don't - 2 dimethoxy groups in certain positions works for phens, but not for trypts.
So, if "twisting" the carbon-tail to a morpholine works in phenmetrazine, I very much believe this would work with a tryptamine too. Only, tryptamines need to be tertiary amines to be any good, so I moved the methyl from the alpha-carbon to the amine. In a way, this is a distant analogue of MET, with the end of the ethyl-group connected with an oxygen to the beta-carbon. The DET analogue of this chemical would have an ethyl in the amine instead of the methyl. Or you could add a carbon to the 3-position of the morpholine, next to the indole, it would be in the same position as the alpha-methyl in AMT. This compound would be very interesting, since it'd have 2 stereocenters.
And of course, there are the possible 4-HO, 5-MeO, 4-AcO etc. groups. So if this chemical would be active, it could create a whole new group of psychedelic tryptamines.
