I can't see as this would be a problem since the area is in compression and you won't be exceeding the line of the neutral axis on the beam. The only problem I can think of is that termite infestation may not be obvious. You can take cores from near the area you want to replace and testing labs have used tapping techniques to determine changes in density of the materials. I think it you pull a couple cores within the replacement area and find them free of tunnels or infestation you would be okay to replace this section.
As for glue - this is one I am not sure about. The compression zone should be sufficient to maintain pressure (the more pressure closer to mid span unless a non-uniform load is used). There is a product called Gorilla Glue that is used in the making of musical instruments and is very good for changes in humidity. You might consider this or a standard builders yellow glue. Possibly others will have a wider choice on the use of adhesives but I would avoid epoxies only because you need time to adjust the filler piece without it first setting up.
Hope this helps you - but remember to investigate areas of the beam that might be subject to potential infestation that can not be seen and which is embedded within the beam and is not readily noticeable by deterioration at the face of the wood.
