Is there a device which acts as a HART slave and Modbus Master? This would enable me to connect an off the shelf modbus RTU slave device to an existing HART installation.
This may be the exact product you're looking for...
check out ProLinx website, http://www.prolinxgateways.com
on their HART to Modbus converter...
Try the Director Series products from Arcom (http://www.arcom.com). We use the DS1 for a HART to MODBUS converter with very good results. I know they can use the DS1 in MODBUS RTU Master mode and convert it back to HART. We were looking at doing this for a project on the Wastewater side, but funding fell through. Great people to work with and very knowledgeable.

Arcom makes some devices that convert from Modbus to Hart protocol. You might check with them for specifics...
I realize this is a little late, but I have the same situation. I came across a device from Microcyber G0310 which I believe will do the job.

This is not too difficult but whether there is a market, I doubt.
The HART interface is implemented with an old modem chip, and then you need a microcontroller to do the Modbus Master bit, with an RS485 interface (assuming you are after RS485 and not Ethernet :) )
We make products (e.g. the KD485-PROG) which will do the protocol conversion part but we never implemented a planned HART interface, due to a total lack of interest.
The prolinxgateways site is gone, the link 404's.
Arcom is so involved in IIoT that it would be a major project to find a HART-Modbus converter box.
The Microcyber G0310 is a Modbus Master that populates HART variables so the HART side is a HART slave.
Interesting concept if one has a HART host system, but such isn't that common. People I run into have HART slave devices that they want to read data from with a Modbus master (HMI, SCADA, PLC, DCS) and there's several vendors who have boxes that are a HART master and Modbus Slave. So I can see the lack of a market for HART slave/Modbus master.
