Can I add a tankless hot water heater to my existing furnace system?

I have an existing gas furnace system and a separate gas hot water heater. I'd like to get rid of the hot water heater because it is taking up too much room, and I want to use that space to fit in a washer and dryer. I have another house where the furnace and the hot water heater are all the same unit without a tank. Can someone modify my existing furnace to attach a tankless hot water unit to my existing furnace, or do I have to buy a whole new furnace to have one that integrates it?

Oil-burning Tankless Hot Water Heater Temperature-recovery Problems.

We have an issue with the hot water supply from a 2004 Peerless oil furnace/boiler with tankless hot water. The shower starts at full temp, but quickly goes tepid (too cool for a comfortable bath/shower, but not ice-cold) and returns to full heat after 5-10 minutes. This is most apparent during the first two showers of the day or bath in the evening - subsequent showers or baths don't seem to have the problem to the same extent. This makes troubleshooting difficult, as we can't tell until an hour or so after running all that hot water to see if the problem returns. It's most pronounced in winter, during the summer the issue seems to go away. (Details inside) [more inside]
