If the area you need is not too large then you can quite quickly still do it with JOSM. The API only permits a maximum 0.25 deg x 0.25 deg data box so split up your bounding box into 0.25 deg maximum parts and import them into JOSM. Import each to a new layer is quickest and then use the merge down to merge them all into the same layer. Alternatively import them into the same layer. Once you are done you can same the final .osm file and then create your img file using mkgmap. JOSM is fine for this process, even for multiple 0.25 deg "tiles" of data, but only so long as each area doesn't have a huge amount of data in it. If there is lots of data then the merge process in JOSM will take some time. If this is the case then moving to a planet extract using osmosis is the logical way to go. For Bangladesh I would suggest you try the JOSM approach first though.
